Behaviour of thin-walled steel frame joints
AbstractWelded thin-walled plate girders play an increasingly important role in steel structures. The provisions of modern codes with regard to design are restricted to the span region between supports. The design of the joint panel is still governed by the buckling load, thus making the application of costly stiffeners necessary. Experimental investigations on such joints have shown that their strength is well above this load, due to the development of a tension field action. To ensure an effective design, it is necessary to make allowance for the postbuckling reserve of strength and to identify possible collapse mechanisms.The present paper provides a method for calculating the carrying capacity and the deformation characteristics of the joints. Static and kinematic limit state models are presented which allow the ultimate strength to be determined from closed formulae. The predicted values are in reasonable agreement with experimental results.
